HAND-STAM P.

SPECIFICATION forming part of Letters Patent No. 570,264, dated October 27, 1896. Application filed June 27, 1896. Serial No. 597.222. (No model.)

To all whom, (it 'nuty concern:

Be it known that 1, JOHN G. OTTESON, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have inventedcertain new and useful Improvements in Hand-Stamps, of which the following is a specification, reference being had to the drawings accompanying and forming a part of the same. I

The invention subject of my present application is an improvement in hand presses or stamps for printing names, dates, and the like, and capable of adjustment, whereby different characters may be brought into alinement in printing position.

The invention has for its object to provide a better and more practicable device for this purpose, and comprises improvements in structural details whereby the movement of the type-bands is rendered more easy, the letters maintained in better alinement, and

the bands held close together without liability of interference one with another. These features of novelty will be described in detail by reference to the accompanying drawings.

Figure 1 is a view in front elevation and part section of my improved stamp. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a vertical section between any two band-rollers and bands of Fig. 1. Fig. 4 is a face view of a modified form of band-roller. Fig. 5 is a top plan View of a series of, such band-rollers of the kind shown in Fig. 4:. ;Fig. 6 is a side bodying the invention, and Fig. 7 is a sec tional view on line as :0 of Fig. 6.

The operative parts of the device are supported in or by a rectangular frame, preferably composed of a bar A with its two longer sides parallel and provided with a knob or handle A for its more ready manipulation. The ends of the said bar or frame are threaded at a and enter openings in or through a block B. Nuts a are provided for adjusting the position of the frame with reference tothe block B, as more fully hereinafter described.

A shaft O is mounted in the frame A by passing through openings in the sides and near its upper end. Upon this shaft are placed a series of wooden or other disks E, their number being arbitrary, which constitute rollers over which run bands D, which carry the letters or characters from which impressions are made. Said bands D may be of any material suited for the purpose, such as linen strips with rubber facings, in which are formed or to which are applied any desired letter or character types. The bands pass around the rollers and over the surface of the block B, the lowermost face of which is of just sufficient width and prominence to contain a complete row of letters and to impress the same upon the surface to be printed. In the preferred form of the invention the rollers E are provided with pins or projem tions 6 in their peripheries, and the bands D are formed with corresponding perforations 01, so that the bands and rollers interengage like a sprocket and chain. The perforations d also provide a convenient means for alining the desired letters by inserting in them any pointed instrument and drawing the band along over the block B and around the rollers E. The portions of the shaft 0 which rest upon the bearings afforded by the openings in the side bars A are of reduced diameter and eccentric to the shaft, so that by turning the shaft the series of disks E will be moved bodily toward and away from the base-block B.

In order to prevent the shaft 0 from revolving, a pin a is set in the outside of the frame A in position to engage with an arm 1), extending radially from the projecting end of shaft 0. elevation of a modified form of stamp em In the use of this device the bands D are first moved to bringthe desired letters into alinement in the printing position.

The rollers E being loose upon shaft 0 permit each band to be brought to its proper position without dist-urbin g any of the others. hen the letters or 1 type have been thus alined, a pin 0 is passed holes in the frame through which said pin passes are, however, somewhat elongated, as shown in Fig. 2, to permit a vertical movement of the rollers while the pin extends through them. To facilitate the introduction of the pin 0 when the letters are only approximately alined, each opening through the disk is made tapering, as shown in Fig. 1. After the letters have been alined and secured as above described the shaft (J is turned by the arm I), so that the eccentric bearingsurfaces 1) will raise up the whole series of rollers and thus tighten all of the bands D. The device is then in condition for making as many impressions from the type alined in the printing position as may be desired.

To print other names or figures, the bands are loosened by turning the eccentric shaft, released by withdrawing the pin 0 and moved to present the desired letters in printingposition. Should only a portion of the bands be required to print a name or word, the others are moved so that the spaces between two consecutive letters will be brought to the printing position. All of the rollers may be fixed in this position if the number of holes through them be twice the number of letters, or one or more blank spaces may be left 011 each band for the same purpose, if desired. Primarily the adjustment of the length of the frame by turning the nuts determines the tension 011 the bands, but in order to permit a free movement of the bands for setting up new combinations of characters this tension is comparatively slight, the final tension for printing being secured by turning the eccentric shaft (1.

In lieu of moving the bands as above described the rollers may be rotated to bring the several bands to their proper positions, and in Figs. 4 and 5 I have shown a convenient means for accomplishing this. Each roller has in this casea series of radial grooves Gin one face and a pin or projection 1" set in the opposite face. The disk 011 the right of the series facing the instrument has a flange D of greater diameter or is secured to a larger disk, as shown in Fig. 5, and the series of disks are pressed together by a spring-blade II, (shown in transverse section in Fig. 5,) interposed between the last of the series of disks and the side of the frame. By turning the disk D its pin f engages with one of the radial grooves G in the next adjacent disk or roller and motion is therefore imparted to the latter. lhe same movement is similarly transmitted to all the other rollers of the series. hen the roller 011 the left-hand end has thus been turned until the desired letter on its band has been brought to the printing position, I insert a key F through a raised plate F, secured to the frame A, into the groove G in the said roller, which in the position of the roller referred to will be immediately under the corresponding perforation in the plate F. This key is of a thickness which permits its ready insertion in the grooves G, butwhen turned ed gewise it forces apart the two contiguous disks or rollers, so that the pin fin one no longer engages with the grooves in the other. Hence the disengaged disk will remain stationary while the others will continue to turn with the disk D". In the same way after the next disk has been brought to the proper position the key or separator is shifted to the proper groove therein and the last two disks of the series will thus be thrown out of engagement with the others, and so on.

The raised plate F has an upright side or flange F, against which the key 1* rests and is prevented from turning. When the bands have been adjusted to position in this manner, the pin 0 is inserted through the holes in the series of disks and the bands tightened by turning the eccentric shaft, as in the previous case.

In order to prevent interference between the bands during their adjustment while maintaining them very close to each other, I provide paths for them either over the rollers or around the block B, or both, on different levels, utilizing the parts which form the paths of higher levels as guides for retaining the bands in the lower. This feature is illustrated in Figs. 6 and 7, and is applicable to all the forms therein described. In Fig. '7 the rollers or disks are shown as alternately of different diameters, a small disk between two large ones. Secured to the frame are metal or other plates L L, which form side guides for the end disks, and plates M M, which form guides for the enlarged disks. The latter form the guides for the smaller disks, as shown. The same plan is applied to the block B by forming channels of different depths in the block and providing the higher paths with guides. In this way the bands are maintained in very close proximity to one another without interference.

This device is especially useful for printing names of persons or places, dates, and the like, which require to be changed only after a number of repetitions.

hat I claim as my invention is 1. In a hand-stamp, the combination with a frame of a series of disks or rollers and typebands passing around the same and over an impression-surface forming part of the frame, means for adjusting the length of the frame between the rollers and the impression-surface, and a shaft with eccentric hearings on which said rollers are mounted, whereby the tension of the printing-bands is regulated by two independent adjustments, as set forth.

2. In a hand-stamp, aseries of parallel endless type-bands in combination with a frame supporting disks therein and astationary impression-surface around which the said bands pass, the frame adjacent to the impressionsurface being formed with paths for said bands on different levels, the higher paths being formed or provided with flanges or guides to retain the bands in alinement, and serving themselves as guides or flanges for the paths 'on lower levels, as and for the'purpose set series of disks or rollers for supporting and moving the type-bands, the said rollers being normally in engagement, whereby the rotation of one rotates all in the series, and a key or separator for separating or disengaging any one or more of the rollers from the others of the series, as set forth.

5.- The combination in a hand-stamp of a series of disks or rollers for supporting and 20 moving the type-bands,the disks being formed with radial grooves 011 one side and projections' on the other and held normally in engagement by spring action, and a key or separator adapted to be inserted into any of said 25 grooves and when turned to disengage the contiguous disks between which it is placed,

as set forth.
